I got to fly on both, and the difference was night and day. At Austrian (btw, why is the name in English on the side of the plane?) it was "Good morning, may I help you with your bag? Have another danish, I know you're nonrev, it's okay, here's the USAToday with the UGA score from yesterday. Another pillow? Thanks for flying with us!" Lufthansa was more like "Your bag is too big (same bag), it is too heavy, it will come on a later flight (it didn't)." Too bad, it was like the difference in customer service between Georgia and Jersey.
